Help please oh no!

👶🏻👦🏻❤️

Hello everyone. I haven’t been on here for a long time. I’ve had a metallic taste in my mouth and all my food tastes like metal. My gums bled with both my first pregnancies and last night my gum was bleeding out of nowhere. I decided to do a test even though I am on the pill. The first one came back with a second line and I nearly hit the floor! But I did like 8 tests after that and they’re all negative. Is it a dodgy test or??
